I loved being 7 and 22. Those were great years.
That's not to say that I don't love waking up every day, or that every year that passes isn't also great in its own way. I have no regrets about any age in my life.
But I think I've been a little more careful to not elevate things to epic proportions since my early 20s, which forces me to downgrade a lot of experiences to being "just okay," instead of fantastic/out of this world, etc. These days I moderate a lot of my life to being "normal," whereas in my early 20s (and younger), everything was new, everything was balls-to-the-wall, I hammered hard on life and told everyone about it. I think I've come to realize just how lucky I am to have a lot of what I do (resources, opportunities, relationships), and I feel guilty talking about it sometimes when I know that so many other people have it worse. I feel like I don't deserve to brag, because I didn't deserve these good things in my life more than anyone else deserves good things (and doesn't get them). So I downplay a lot of my life, when I'm interacting with most people, just to keep things on an even keel.
So while I do believe that my quality of life goes on unabated, I've learned to tone down my hyperbole in describing what I'm going through. It helps me stay more balanced and not to expect fireworks from everything I experience.
In hindsight, though, I can rave about being 7 and 22.
